'TJGUBZPCKET CAGE FOR ROLLER-BEARINGS.

Application led August 20, 1917.

To r/ZZ '1o/oni it may concern.

Be it known that l, Timor V. Bnciiwaif run, a citizen ot' the United States, and a resident of the city oi' Canton, county of Stark. and State oi Ohio, have invented a new and uset'ul improvement in Doublellocltet Cages for Roller-Bearings, ot' which the following is a specification.

This invention relates to roller bearings, and consists vin the construction and conibi nations of parts he cina'fter described and claimed.

Its objects are to accommodate a larger number of rollers lin a cage of a given size than is possible with other cages, and to provide a cage which is strong and durable, and simple and economical to manufacture.

In the lrawing, which forms a part of this specification and wherein like reference numerals refer to like parts wherever they occur,

Figure l is, an end View of a bearing embodying my invention;

vFig. 2 is a longitudinal section thereof on the line 2 2 in Fig. l;

Fig. 3 is a side View of the assembled bearing; and

Fig. t is a cross-.section on the line t-fl in Fig. 2.

A conical` cage l consists of annular flanges Q connected" at their inner circumference by bridges 3. The bridges 3 have outwardly turned wings l extending the greater part of their length and forming pockets 5. The bridges spaced apart so that each pocket 5 is large enough to contain two rollers 6. The wings 4 extend substantially the length of thebearing surfaces ol thc rollers 6, and theirsurl'accs are concave in order to conform to the rollers. The rollers are of conical form with narrow necks 7 adapted to coperatewvith an annular rib 9 on the smaller end of the inner bearing member l0. The parts of the bearing, are assembled bydetlcctingr thc flat portion of the bridges adjacent to the smaller annular flange sufficiently to permit the cage l and rollers 6 to be forced over the rib 9 of the inner bearing member 10. The bridges and wings are then forced into proper Working position.

Owing to the fact that each pocket is made large enough to accommodate two rollers, less material is usually needed tor the construction of the bridges under the 'Specification of Letters Patent.

wings than would be required with a cage wherein each pocket accommodated a single roller. As a consequence, more rollers may be used and still have wings oi' ample Width. It is noted that 'the wings are illustrated as terminating short of the ends of the bridges. The in'incipal reason for this construction is l to che-apen the cost of pertoratingr and wing-v ing the cages, as this construction Vlends itself to a long continuance ol the life of' the punches and dies. So, too, by putting two rollers in each pocket, rollers of smaller diameter may be used than would be possible it' a single roller were in each pocket.

The cage is made of a single piece of pressed steel. The cage as shown in the drawing is used with tapered rollers, but 'it is adapted for use with cylindrical rollers.

Other modifications may be made without departing,r from the invention.

I claim the following as my invention:

1. A one-piece cage ot' pressed steel comprismer annular end flanges disposed crosswise ol the axis ot the cage connected at arranged to form pockets. each of which rec ceives and retains two contacting rollers.

y3. A cage comprismg annular end flanges connected at their 'inner circumferences by bridges, said bridges having outwardly eX- tending wings along their margins and ter-- minating short of said end flanges, said wings beingr spaced apart to form pockets adapted to receive and retain twocontacting rollerseach, and the inner surfaces of said. wings conforming to said rollers.

ft. A roller bearing comprising an inner bearing member, a rib near one end thereof, rollers having grooves to coperate With said rib, and a cage t'or said rollers, said cage comprising annular end flanges connected at dislocation of said i ller bearing comprisingg,- an inner l I f gember, a, rib near one end thereof, rollas mirino' grooves to cooperate .with said rib, :in a e e for said rollers, said cage eomprisnligannuler end flanges connected fit heir in er eirenmferenees by bridges, seid bridb "ing wings extending outwardly to orm po lets for thev rollers, each of said pockets eo taining :i plurality of rollers, end the inner surfaces or said wings eonforming to the adjacent surfaces of said rollers, whereby they prevent accidentel dislocation of said rollers from said enge and inner bearingmember.

i3. A ene-piece enge of pressed steel comprising annuler end iinnges connected by bridges, seid bridges having winds terminoting short of seid end flanges ano. forming pockets, each of which contains two eontaotin@r rollers, the outer throat of the pocket bein?,l narrower than the snm of the diameters ne'rollers therein i roller beni comprising an inner ing` member having an annuler rib near one end, llerehavine grooves to cooperate "s, each of said.

ineens-e terminatingr short of said end flanges, seni wings forming pockets adapted to receii and retain two rollers each.

S. The process oit' assembling the parts of a conical roller bearing,1 wherein two conical rollers are retained in each pocket of e Cage between inner and outer bearing,` members which consists in deiieoting the bridge members of the enge to widen the pockets et their mirrower ends, placing two rollers in each pocket, moving smid inner bearing members endwise into position, restoring said bridge members to initial position, and positioning the outer beni-ing member.

9. The process of assembling the parts 0f :i conical roller bearing wherein two grooved coni al rollers nre retained in each pocket of a onge between inner and outer bearing meinbers, the inner of which has an annular rib thereon, which consists in deiieoting the bridge members of the ciige to widen the pockets at their narrower ends, placing two rollers in ezieh pocket, moving said inner bearing member endwise into position, restoring said bridge members to initial position, :ind positioning the outer bearing member.
